APPARATUS FQR EAISIi-IG SUNZZEN LOGS.

Application filed March 13 T 0 all to 7mm it may concern 'Be it known that I, ROY A. RANGER, a citizen of the United States, residing at Charlevoix, county of Charlevoix, tate of Michigan, have invented a certain new and useful Improvement in Apparatus for liais ing Sunken Logs, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to lifting sunken logs, and'has for its object an improved arrangement of parts capable of easy and accurate assembling and disassembling, by means of which salvaging operations-therefor may be conducted at a minimum of expense and effort, and with reasonable certainty of recovering a suitable proportion of the logs grappled. Such material is generally encountered in the beds of relatively small lakes and streams. often difficult of access, and especially in the case of small streams, so relatively shoal and full of obstructions, that at best a steam or gasolene launch of light draft only could be em ployed, and if employed, the bulk and weight of the logs recovery would soon prove prohibitive relative to its carrying capacity.

apparatus for Furthermore, if the small lake, for example,

has no outlet or communication with a larger body of water, on which the regular maintenance of a tug or launch is hardly worth while, the cost of transporting such a vessel overland, and then getting it afloat upon the lake where the logs are to be sought, would be prohibitive. A relatively low rate of speed being all that is needed in a craft used for trolling for such logs, though a large proportionate buoyancy be ing equally desirable, small scows or lighters, propelled by paddle wheels and preferably assembled in catamaran formation, meet this need most suitably, particularly if the mechanism employed for propulsion be of such a type that it can also be connected up for the lifting of the logs when grappled. Hasty and unskilled setting up of such mechanism on improperly associated floats, I have found, however, often results in disabling effects upon the mechanism, due to the inability of the assembled parts to properly resist the diverse strains placed thereon,

To this end I have devised an organize,

represents a bed or base t m near whose ends are locatedsupportin struts B. wherein are .z'otatably jOlHHZElQd fhQ parts of the line shaft C, with whose ends the shafts of the paddle wheels D are operatively connected as by the endless chains passing over the sprocket wheels P and Q. This base timber i 's designed to be fixed transversely of a pair of lighters in such position that the paddle wheels D dip into the water on the outer sides thereof. i ot only is the base timber A adapted to be se cured so firmly, though detachably. to the lighter members E, to ui e rigidly l them in desired relati e end por ions of the li,

of my apparatus be united b the detachable cr-c naces Fl An operators pla rm may also be placed across the spa a between the lighters. Adjacent the shaft on one-of the lighters is located a power plant of ZEHfJ dGSlIOCl type, such as a gasolene engine, which may be operatively connected with the shaft C in any desired manner, as by the endless chain T, gears or the like, so that the paddle wheels may be actuated. These parts of the line shaft C, as M and S, while in axial alinement, are adapted for independent connection as for example, by means of clutch members K, with the engine H, so that one or the other of the paddle wheels may be operated while the other is at rest or rotating in the opposite direction, for steering or turning the united floats or lighters; if the clutch connections for both shafts are thrown out, the movement of the lighters through the water ceases.

Located adjacent the shaft 0 is a second shaft J which may be thrown into operative connection with the power plant, or disconnected therefrom, as by the endless chain V, or intermeshing gears, to cause its rotabeing grappled for.

tion, and consequently the winding up or paying out of the cable L from which the log grapples are suspended. The bearings N wherein this second shaft J is journaled may be also permanently supported upon a similar base timber WV, or, if desired, may be fixed directly on the decks of the lighters.

All strains due to the operation of either shaft and its connected parts are thus directed against their base timbers A and W,

and since these parts are permanently associated therewith in proper r0 table position, no displacement or twisting strain thereupon can occur in case the two lighter members tend to work back and forth more or less under the strain of operation. W hen disassembled each base timber and its supported shaft is removed as single inseparable unit, and the detachment of the base timber A from the lighterE by the detachment of itscross brace piece F, enables each lighter to be hoisted out separately and placed upon skids or a wagon for transporting, the loose and interchangeable connection of the power plant therewith being such that no difficulty or adjustment for connection when the shafts are again assembled is encountered.

As brought out particularly in Fig. 4;, the cable drum X may be moved from one end of the shaft to the other, it being keyed to rotate therewith, so that as a log is lifted between the lighters, it may be drawn to one sit e or the other for chains Y to be attached, to hold it against sinking while the logs are The next log raiser may be similarly drawn against the side of the other lighter and there have similar chains V looped around it.

What I claim is:

1. In combination with a pair of lighter members, means for detachably uniting the same, a base timber having an operating shaft rotatably supported thereon, adapted for detachable connection with the lighters, a second shaft rotatably supported in parallel relation to said operating shaft, a

power plant carried on one of the lighters,

and disconnectible power transmitting means whereby said shafts may be operatively connected with said power plant.

2. The combination, with a pair of lighter members, of a base timber adapted for rigid attaclnnent, transversely thereof, a shaft rotatably journaled lengthwise of said base timber, a second shaft with which a hoisting cable may be connected, and means adapted for operative connection with and detachment from one or the other of said shafts whereby either may be operated independently of the other.

3. The combination of a pair of lighter members, detachable means for holding them in spaced relation to one another, a base member carrying a rotatable shaft detachably secured at its ends to said, lighter members, a power plant operatively connected with said rotatable shaft, a pair of paddle wheels rotatably supported on the outer sides of said lighter members, means for operatively connecting said paddle wheels with said power plant, and a rotatable cable drum adapted to be operatively connected with said power plant. 1

4. In combination with a pair of lighter members, a base timber detachably secured transversely thereof, a rotatable shaft on which a cable is wound, a power plant, aretatable line shaft deriving its actuation from said power plant, means for operatively connecting the first named shaft with said line shaft, and a pair of paddle wheels rotatably supported on the outer sides of said lighters, adapted to be thrown into and out of operative connection with said line shaft.

In testimony whereof, I sign this specification in the presence of two witnesses.
